The G-209A line of shackles is much like the famous G-209 series, only better. They are better because they are made of alloy steel and boast higher Working Load Limits (WLL) on a size-to-size basis. For example, a 5/8" G-209 is rated at 3-1/4T while a 5/8" G-209A is rated at 5T. This means you can achieve a higher Working Load Limit without stepping up in size, and many users find that to be a great advantage. They feature a hot-dip galvanized finish, a strong 5:1 safety factor and are fatigue rated.
